    Can anyone tell me how to copy one directory structure to another (Same layout and same name). All I want to do is to copy new or modified files and directories. If the dir exists then only update the files that have changed. Hope that makes sense?

    You could use unison (I think that's what it's called).

    rsync -av --delete <source> <backup>

    will copy only the updated files over and delete files in the destination that do not exist anymore in the source

    man cp:

    -u, --update
    copy only when the SOURCE file is newer than the destination file or when the destination file is missing
